I’m not sure what the right solution here is, or if there is one. Basically I have a state machine in a PLC that is skipping a step somewhere, somehow. For some other reasons, it probably won’t be possible to try and monitor the PLC to find out whats skipping and how, so we’re going to try and catch it in Ignition, but I think that means having a very, very fast scan class. I haven’t been able to find good resources on just how fast a scan class can be - I’d guess the technical min is 1ms, but is that feasible? For how many tags?
Has anyone tried this kind of thing before? Any other suggestions for finding this kind of thing?
